GHECK-OANOELING ATTACHMENT FOR FOUNTAIN PENSV Application filed February23, 1323, Serial No. 620,714. Renewed August 20, 1924.

To all whom it may concern:

Be it known that I, Pnnno ESCALAMBRE RIOERRA, a citizen of thePhilippine Islands, residing at Manila, in the Philippine Islands, haveinvented certain new and useful Improvements in Check-CancelingAttachments for Fountain Pens, of which the following is aspecification.

in accordance with this invention, provision is made for a fountain penattachment whereby indentations or scoring may be accomplished by theattachment on checks or other commercial papers thus preventing raisingof numerals or otherwise changing commercial papers, and with theattachment always in accessible position for use.

In accordance with the invention, there is provided a check receivingdevice of elastic nature permitting the introduction of the paper to beprotected in the protecting device so that by a single blow of the handthe paper is indented or scored in such manner that its surfacecontinuity is broken and the check cannot be changed without suchchanges becoming apparent, and so an intention to raise the check isdefeated bcause such attempt at raising the check becomes at onceapparent and is thereby foiled.

The rear handle portion of the pen device is made of such nature as tobe surrounded by a compressing device tending to bring the two parts ofthe handle into closed position to he received and contained within thecompressing device or holder.

The device is of such a nature that the impress of the scoring device inthe paper though readily brought about by a simple blow of the hand issuiiicient to leave the impress of the scoring devices and such impresscannot be thereafter obliterated because of the rupturing of the fibersof the paper, and any attempt to obliterate the imprint of the scoringdevices will result in the production of a disturbance of the paperfibers which cannot thereafter be changed.

The invention will be best understood. from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawings forming part of this specification, with the understand ingthat the practical embodiment of the invention is susceptible of changesand modifications, so long as such changes and modifications mark nomaterial departure from the salient features of the invention asexpressed in the appended claims.

In the drawings Figure 1 is a partial longitudinal section and a partialelevation of a fountain pen body equipped with the invention.

F 2 is an enlarged view of the structure shown in Fig. 1 showing thebase end of the handle having a normal spread imparted to it to permitthe introduction of the check or other commercial paper to be protected.

Fig. 3 is a cross section on the line 3 3 of Fig. 2.

Fig. 4 is a longitudinal section of the basic end of the fountain penarranged to receive the scoring devices attached thereto.

Referring first to Fig. 1, there is shown a fountain pen body or handle1.

The construction of the fountain pen body need not differ from thatusually employed and consequently the fountain pen handle needs nospecial description.

Attached to the base end of the fountain pen is a bifurcated member 2,comprising the body portion of the device which may be of hard rubber orother appropriate material providing the longitudinal slot 3 havingindentations or serrations. Covering the furcations upon their innersurface is a substantially U-shaped metal lining 5 having formed uponits opposed faces raised teeth t so arranged that when the legs of thelining are pressed together, the teeth will mesh. A screw 6 is providedto retain the member 5 in position between the furcations of the member2.

The serrated or toothed lining at the end of the fountain pen handle,admitting the check or other paper between the jaws thereof, has the twomembers of the split end approachable close enough to impress the teethend into the paper and more or less disturb the fiber of the paper toimpress the distortion sufliciently into the paper to partially dislodgethe fiber so that the fiber will have sufiicient distortion ordisturbance to render it impossible to smooth out the paper sodistorted.

When the device is not in use the jaws of the member 2 are forcedtogether against thetension of the spring legs of the lining 5 and a cap7 is clipped thereover to protect the device.

In Fig. 2, the yieldable end of the fountain pen is shown removed sothat the spring legs of the member 5 spread sufli-- ciently to permitthe introduction of the check or other paper document into the base endof the fountain pen for impression ofthe paper and the indentation ofthe substance thereof.

The subject matter of this application provides a very convenient anduseful artiole for the use by writers, especially bankers desiring toprotect checks which they draw with the check protector always inconvenient position for use and as the tonntain pen is not liable to bemislaid, it will always be in convenient position for use.

What is claimed is 1. A check protector comprising a bifurcatedresilient body member, a substantially U-shaped member secured at theinner end between the turcat-ions of the body member and serving tonormally retain the furcations extended outwardly, and teeth formedintegrally with and upon the opposed inner faces of said U-shapcd memberand posi tioned in a manner as to cause them to mesh when the parts areactuated.

2. A check protector comprising, a bifurcated resilient body member, asubstantially U-shaped member secured at the inner end between thefurcations of the body member and serving; to normally retain theureations extended outwardly, teeth formed integrally with and upon theopposed inner faces oi said U-shaped member and positioned in a manneras to cause them to mesh when the parts are actuated, and means forholding and en iasing said protecting device in closed position.

In testimony whereof, I ailix my signature hereto.
